Planting & Establishment
First growing seasonYoung tree with bare or container-grown roots being planted in prepared hole
Water thoroughly after planting. Apply 2-3 inches of mulch around base, keeping away from trunk. Support with stake if necessary in windy locations.
Vegetative Growth
Years 1-3Tree develops branch structure with compound leaves (pinnately arranged leaflets) and establishes root system
Water regularly during first 2-3 years. Prune to establish central leader and desired form. Remove crossing or damaged branches.
Flowering
Spring (April-May in northern zones)Small white or cream flowers appear in flat-topped clusters (corymbs) in spring
Flowers attract pollinators. No special care needed; do not deadhead as berries will develop.
Fruiting
Summer into fall (June-November)Small round berries develop from flowers, initially green, ripening to orange-red by summer
Continue regular watering. Berries persist into fall and attract birds. Do not prune heavily during this time.
Fall Color & Dormancy
September-NovemberFoliage transitions through yellow and orange to brilliant red; berries remain vibrant; leaves drop by late fall
Peak ornamental season. No pruning during this time. Stop fertilizing in late summer. Rake fallen leaves if desired.

Fun Facts
- 🌱 Autumn Brilliance is a hybrid cross developed to combine the ornamental qualities of Asian and North American rowan species, resulting in superior fall color compared to either parent species.
- 🌱 The name reflects the tree's dramatic fall transformation—a single tree can display an entire spectrum of warm colors from yellow through orange to brilliant scarlet within 2-3 weeks.
- 🌱 Rowan berries are not true berries botanically but rather pomes (like apples), and they can persist on branches well into winter, providing crucial nutrition to migrating birds.
